9-26ENGINE <1.8L Engine> -Service Adjustment Procedures
TIMING BELT TENSION ADJUSTMENTNOSFGBCThere are two access holes provided in the timing belt front
lower cover. The two access holes can be used to readjust thetension of the timing belt, by following the procedures
described below, without the necessity of removing the timing
belt front lower cover. Note, however, that timing belt “B”,
which drives the right silent shaft, cannot be adjusted unless
the cover is removed.
(1) Turn the steering wheel all the way to the left.
(2) Remove the left side undercover panel.
NOTEThis work is done so that the crankshaft can be turned.
(3) Place a piece of wood against the engine oil pan and jack
(4)
:tmove the engine mounting bracket.
(5) Remove the timging belt front upper cover.
(6) Remove the four spark plugs.
(7) Turn the crankshaft clockwise and check the timing belt
condition.

(9) Remove the air conditioner drive belt and the alternator
drive belt.
(10)Remove the access cover (two places). There are easily
removed by inserting a screwdriver into the slots indicated
by the raised arrows in the timing belt cover and twisting.
(1l)lnser-t a socket wrench [a 14 mm (.55 in.) box wrench]
through the hole in the access cover and loosen the timing
belt tension bolt and nut.
Caution
The timing belt tension bolt and nut need only be
loosened
180”-200”. Any further loosening might re-
sult in their falling off inside the timing belt cover.
